Comment # 6 on bug 1220569 from Roger Whittaker

I can't do this because I don't know how this BVCP thing works.  It's a web
application that spawns a browser window called a "VNC console" which is using
noVNC.

If I look at the system where BVCP is running I don't see an open VNC port, so
I can't connect with another VNC viewer.

8086 is the port where the management web page side of it is accessed. 

noVNC is a javascript VNC client that runs in a browser.
